No, Havana Brown cats are not typically polydactyl. Polydactyly is a genetic trait that causes cats to have extra toes on one or more of their paws. While some cat breeds, such as the Maine Coon and American Bobtail, are more commonly associated with polydactyly, it is not a characteristic trait of the Havana Brown breed. Havana Browns typically have the standard number of toes, five on each front paw and four on each back paw.
